fwupd : Mettre à jour les firmware et BIOS depuis Linux

Table des matières

Introduction



Dans cet article, nous allons voir comment mettre à jour les firmware (micro-logiciels) de notre PC depuis Linux.
Cela va se faire avec le logiciel fwupd

Les informations sont celles de Linux Vendor firmware Service (LVFS) https://fwupd.org/

Installation



Sous Gentoo, on prendra soin d'activer quelques USE, dans mon cas celui de DELL est très important :

Code BASH :
echo "sys-apps/fwupd dell uefi synaptics tpm nvme thunderbolt" >> /etc/portage/package.use/custom


Puis on installe fwupd :

Code BASH :
emerge -av sys-apps/fwupd


Pour le monde RedHat :

Code BASH :
dnf install fwupd


Utiliser fwupd



Une fois le logiciel installé, on pourra vérifier les matériels utilisés supportés avec :

Code BASH :
fwupdmgr get-devices


Voici un retour sur un Dell Latitude 3510 :
